filtering out mode-change-only changes

What is the best way to filter out the "mode change only" entries from a "name-status diff result" listing of changed files?

Reason-for-this: get a list of files whose content changed and feed that list into a gui-diff-tool for visual review of "merge" (rebase) results.

Partial-Solutions: --name-status does not have mode-change info. --raw has mode change info but I would have to parse it out and compare it myself. --summary has that info, but not the content modification info.

Before I write a script to discern "mode-change-only changes" and remove them from the list of changed files (thus leaving only content-changed files in the list), I'd like to see if there is some way that git already-does-this-for-you, or if someone already has a script that does this.

Thanks in advance for any tips.
